Multifunctional eye health-care therapeutic apparatus and work control method thereof

Abstract

The invention discloses multifunctional eye health-care therapeutic apparatus and a work control method thereof. A first gear and a second gear are meshed with a first gear rack and a second gear rack respectively, an inner shell and lenses can move left and right with an outer shell, a motor drives a threaded rod with two reverse ends to adjust left and right movement of the outer shell, and therefore the center distance of the first lens and the second lens is adjusted; when a second driving gear rotates, a stepped gear moves back and forth, a pushing rod is hinged to a first connecting rod and a second connecting rod, the angle of the first lens and the second lens is adjusted, and when the angle of the first lens and the second lens changes, the first gear and the second gear keep synchronous rotation, and the first gear and the second gear are meshed with the first gear rack and the second gear rack respectively to generate left and right displacement, so that dynamic microspur adjustment of the centers of the lenses is achieved. The multifunctional eye health-care therapeutic apparatus is simple in structure, the center distance of the lenses can be freely adjusted according to needs of a user, the stereoscopic vision effect is good, far and near vision disparity is obvious, and the treatment effect is remarkable.

Description

technical field [0001] The invention relates to a multifunctional eye health care treatment instrument and a working control method thereof. Background technique [0002] Eyes are the windows of man. At present, due to the popularization and application of various electronic products, there are more and more myopia patients. According to the latest statistics from relevant departments, the incidence of myopia among primary school students is 13.6%, that of middle school students is 46.25%, and that of college students is as much as 70%. [0003] There are more and more products related to eye therapy instruments. In the existing technology, the left and right monitors are used as visual targets, and they move obliquely from far to near during work. The visual targets are positioned at the center of the monitor, and the maximum center distance and minimum center distance It is fixed, and the center distance between the two lenses is also fixed, which cannot match the pupil ...

AI Technical Summary

Problems solved by technology

[0003] There are more and more products related to eye therapy instruments. In the existing technology, the left and right monitors are used as visual targets, and they move obliquely from far to near during work. The visual targets are positioned at the center of the monitor, and the maximum center distance and minimum center distance It is fixed, and the center distance between the two lenses is also fixed, which cannot match the pupil distance of most users. When the visual target reaches the near point, the picture enters the eye through the secondary optical axis of the lens, and the imaging quality deteriorates. Design value deviation increases

All the video materials watched during the treatment cannot always have the elements that cause central vision excitement, there is no difference between paracentral fixation and central fixation, the stereo vision is poor, and the sense of distance is not obvious, thus affecting the treatment effect
